Thecus N4310 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from N4310.

How to recover data from NAS Thecus N4310

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Thecus also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can data be lost during the process of upgrading or updating the NAS Thecus N4310 device's firmware?

Yes, there is a risk of data loss during the process of upgrading or updating the firmware of Thecus N4310 NAS device. It is always recommended to backup all important data before performing any firmware updates or upgrades. While the manufacturers take precautions to minimize the risk, unforeseen issues or errors during the update process can potentially result in data loss. Therefore, it is crucial to have a backup to ensure the safety of your data.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS N4310 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Thecus N4310 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

      Yes, it is usually possible to recover data from a NAS device like Thecus N4310 even after a system update or software upgrade. However, it depends on the specific circumstances and the extent of the changes made during the update.

      If the update process was smooth and did not result in any data loss or corruption, you should be able to access your data as before. In such cases, the update typically only affects the operating system and software components, leaving the user data intact.

      However, if there was a problem during the update process, such as power failure, interruption, or other issues, it could potentially lead to data loss or corruption. In such cases, data recovery may be required.

      To recover data from a NAS device after an update, you can try the following steps:

      1. Check the NAS device: Ensure that the NAS device is functioning properly and can be accessed. Make sure all connections are secure and there are no hardware issues.
      2. Consult the manufacturer's support: Thecus provides support for their devices, so you can contact their technical support team for guidance on recovering data after an update. They may provide specific instructions or tools to assist in the recovery process.
      3. Use data recovery software: If the NAS device is not accessible or the data is corrupted, you can try using data recovery software specifically designed for NAS devices. These tools can scan the NAS device and attempt to recover lost or inaccessible data. Some popular options include R-Studio, EaseUS Data Recovery Wizard, or GetDataBack.
      4. Professional data recovery services: If the above methods fail to recover your data, you can consider seeking professional data recovery services. These services specialize in recovering data from various storage devices, including NAS devices. They have advanced tools and techniques to handle complex data recovery scenarios.

      Remember to always have a backup of your important data to avoid data loss in case of any unexpected events or issues during updates or upgrades.
